14-Days of Data from the Tualatin River at Highway 219 (14206241)

Streamflow, estimated

During periods of high water, discharge data may not be available
because the water depth may exceed the range of the rating curve.
Streamflow data are considered as estimated for this site because a
relatively old rating curve from the Oregon Water Resources Department is
being used.

Dissolved Oxygen

In the graph below, "Data" are the raw data, "No supersat." are
the half-hourly data with a ceiling of 100% saturation, "7-day mean"
represents the 7-day running average with no credit for supersaturation,
"7-day mean min" represents the 7-day running average of daily minima with
no credit for supersaturation, and "30-day mean" is the 30-day running
average with no credit for supersaturation. The red line will often plot
on top of the black one. If the 7-day or 30-day lines are not plotted,
it is due to missing data in that period. "Saturation" represents the 100%
saturation value for dissolved oxygen.

Oxygen Percent Saturation

Data in the graph are plotted against the axis of the same color.
Percent saturation is estimated as a function of water temperature at this
site and barometric pressure at a nearby site.
